On the record

Best explained

Tarek Mansour explains why insider trading structurally destroys prediction market liquidity. Toxic informed flow causes market makers to pull quotes, collapsing the liquid market needed for scale.

“The greater reason is actually like a market structure reason which is like once you have a lot of toxic flow of like informed traders coming in market makers aren't going to quote anymore liquidity providers are going to pull their quotes and therefore like no one will have a liquid market to trade against and then you just have to draw this line against insider trading if you want to have market integrity and healthy markets that thrive and scale.”

Company & tool watch

Kalshi, the prediction market platform whose CEO publicly compared it to a cure for Instagram addiction, is expanding toward real-money wagering and potential integration into Meta social apps.

“Tar Matsur the CEO of Khi recently literally compared gambling on Khi and other prediction markets as the cure to Instagram addiction.”

Contrarian take

Kalshi predicts sports will quickly fall to just 20 to 30% of total prediction market exchange volume as financial and macro markets grow, inverting the current public perception that sports betting dominates the sector.

“Sports quickly go from where it is now to becoming like only 20 to 30% of the exchange volume.”
